Fish,
960hp should be enough to set most anchors.
I only have 40hp and use less rpm (a tad).
There's a thread on rpm to set anchors. You may find it interesting. I suppose a formula could be created that would dictate how much reverse thrust should be used to set anchors. Of course every anchor is a bit (or lots) different and that dosn't compare to how different a sea floor can be.
See See Steve's "Anchor Setting Videos" thread. He also has a 40hp engine and set many anchors about 40lbs .. in a soft bottom.
I've seen quite a few studies on how much wind creates how much drag but I've not thought any were very close to reality.
The next time you're anchored in a strong wind look at the rode and notice details. Then come as close as you can to duplicating it. That may be of some help.
The only time I've anchored at 10-1 it was just because I could. Almost never have I anchored where 10-1 scope is possible so I polish my short scope act. And choose my anchors accordingly. I own 11 anchors and all are good at short scope.
